Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82816, here are decompositions:
- 3 + 82813 = 82816
- 5 + 82811 = 82816
- 17 + 82799 = 82816
- 23 + 82793 = 82816
- 29 + 82787 = 82816
- 53 + 82763 = 82816
- 59 + 82757 = 82816
- 89 + 82727 = 82816
Showing the first eight; more decompositions exist.
